Is your PC recognizing the gTab in APX mode (Power and Vol [-])? Does nvflash complete? Post screenshots.

usb not recognized, tablet goes into apx but the computer does not recognize it. I have tried several different driver combinations and it still cant' see it. I think that I somehow screwed up the driver in the tablet. but can't even get it to connect to the computer. I tried a linux connection and it didn't recognize it either. I was using a live cd and tried to get the startup to locate a driver, no such luck. Is there a way I can completly format the tablet??? I can't get it past the boot loader error. thanks for your input up to now. hope someone has answers for me. I may have created a very nice parts machine.

You can't screw-up the APX-mode USB driver on the gTablet--it's built into the system firmware --ie. it's hard-coded. A HW error is a more likely culprit (if, indeed, the PC doesn't see the tablet in APX mode) . Disassemble the gTab and carefully inspect the USB port and surroundings for stray bits of metal, or solder, or cut traces, etc.

Since you can use Linux, do this:
1. Boot into Linux.
2. Put the tablet into APX mode (the screen will turn off).
3. Plug the cable from the tablet into the PC.
4. Run these command (only the stuff in bold) and post their output (or a screenshot):

Thank you in advance!

Daft one, but have you tried another USB cable?
No I have not, but when I plug it in a dialog box comes up with something like "Device Not Recognized" and on the screen of the phone it prints the
Code:
-- suspend --

-- portchange --
etc.
So the connection is made, just the computer doesn't realize it.
Again, when I enter the command

there is no response.
I do have drivers installed.

Ordinarily, I use Odin within a VirtualBox Vista install, but as Linux is reporting the problem, that renders VirtualBox useless. I don't really want to re-install Vista on my PC, as it will mean a lot of hard drive partition shuffling including deletion of one of my Linux installs just to make room for a Windows install which I'll very rarely use.

A few questions first:
1) Any Linux users solved this without using Windows?
2) Might I find after installing Windows, that the problem is not with Linux?
3) Is there some other way of reseting the phone?
Thanks for any help.

Which USB drivers would they be? I'm not being funny, but have you even read the title? I'm using Linux. I don't need to install USB drivers.
#edit2
At least, I don't need to install USB drivers for any device which operates in mass storage mode, which was what the device was operating in before I bricked it.
I don't know what protocol the device operates in when in Download Mode... it wouldn't be Media Transfer Protocol (MPT) by any chance?
I followed these instructions for my Galaxy Tab 2.0

First remove and select delete drivers from Device Manager in control panel. Then remove cable from usb port. Install the drivers dont connect cable. Reboot computer. Take battery out. When pc fully boots plug cable to phone. Enter odin mode (vol up + vol down + power). When you see warning screen immediately plug cable to pc in other usb port. Select odin mode in phone and wait drivers to recognized. Open odin to see if com port installed. Then flash one of the original firmwares.

Hi ChelebiTech, thanks for replying. Taken me a long time to get around to doing this, partly because I really really really did not expect that to work. But unbelievably it did, and my gt-s5830i is now recognized by Odin v3.0.7. Good stuff.
However, I'm really struggling to navigate my way around all the available information on here. I don't know if I should first try flashing a new recovery, because I cannot enter recovery mode, or try flashing a stock firmware.
I've been looking at flashing the stock firmware but I can't find any exact firmware matches from the details I've written down before my failed flash attempt.
I wrote down:
Sales Code: BTU
PDA:S5830iXXLD3
PHONE:S5830iXXLD2
CSC:S5830iBTULC1
Using the firmware checker on samsmobiles.com, the closest match I find is
PDA:S5830IXXLK3
CSC:S5830IBTULK1
MODEM:S5830IXXLK1
As far as flashing a recovery goes, what are my choices if I can't use any recovery mode in the first place? Is there a recovery I can flash?
Thanks for any help.

Hi,
Yesterday a friend of mine gave me a LG L9 (P760). Some months (or maybe years) ago he changed this phone for a new one and stored it without battery. 2 days ago he tried to turn it on but no life, same result when he connected it to the wall charger.
I tried connecting it without battery to the PC (on Ubuntu, if I use windows 10 the device keeps disconnecting and connecting and I can't install the OMAP4430 driver because win says they are already updated (it isn't so, uses the driver for "usb enumeration failure")) and is recognized, via lsusb, as "ID 0451:d00f Texas Instruments, Inc.".
If i launch dmesg it gives (more than one time):
Code:
[ 973.692035] usb 1-6: new high-speed USB device number 26 using ehci-pci
[ 973.825080] usb 1-6: unable to get BOS descriptor

.
I tried using the method suggested here: http://vincenzoml.blogspot.it/2013/08/lg-l9-unbrick-script.html. I can get into fastboot but then it says
Code:
sending 'u-boot' (1024 KB)...
OKAY [ 0.675s]
writing 'u-boot'...
FAILED (remote: partition does not exist)
What can I do? Is there a possibility to make this phone work again?
Thanks in advance to all!
Under Win7 i had both the LG drivers and the Google SDK drivers installed. Under Win10 also, but the Google drivers can't be found in device manager. Anyway, in contrary to Win7, the LG drivers and LG software xan niw detect my phone and work, with the exception of Fastboot. Under Win7 and with a custom rom, LG drivers were only good to provide a virtual com port in D/L mode.
And the morale of this tale: These outdated OMAP drivers were never of any use to me.
That's the normal behavior of the OMAP Chip, the only thing you've to do is to re-flash putting back the battery and then, connecting your device over USB while holding Vol+.
Ah, no battery. While it's sometimes recommended to remove the battery during unbricking, i think it's simply impossible to do this or anything w/o battery, despite the 0,5A power via usb.
After a failed attempt to invoke D/L mode, you can remove the battery shortly, or switch the phone on and (force) off for an extra time, to try again. Otherwise it's more likely that D/L mode will again fail.

I have the battery! The problem is that fastboot can't find the partitions
If the first hurdle has been passed, and there is actual access to the phone(i'm not sure whether this is the case here), the partitions really got deleted or damaged. Unbricking with a stock rom is the only option. Or professional service (better a new phone) if that ain't possible.
Can't you try this, please? http://forum.xda-developers.com/showthread.php?t=2546571 I've found it on the forum just a couple of minutes ago, I hope it helps .
Good luck!
I have the same problem.
If x-loader and u-boot partitions does not exist, we do not have the bootloader, and you can't do anything to make the phone work aside from JTAG.
I tried to boot recovery from computer without flashing using 'boot' command (fastboot boot recovery.img) and this still doesn't work because I don't have bootloader.
Method from post above does not work for me.
Hi... I'm trying to be as concise and as detailed as possible here:
OK.. I'm trying to flash this ulefone S8 Pro with the STOCK ROM from the ulefone website. I'm using Debian Linux and the SP Flash Tool 5.1804.00 for Linux. I've disabled modemmanager (no conflict there) and I'm able to see from the logs that the device is recognised.
The device itself had it's stock boot.img flashed with a patched version (MagiskManager)and the boot loader has been unlocked - and all was working fine... someone decided to mess about deleting files from /system and the phone refused to boot.
So.... I took the device back and flashed boot, recovery and cache from the stock image using fastboot - all fine... then when it came to system.img - I found out that system-sign.img from the stock ROM wouldn't flash via fastboot - I got an error saying something along the lines of:
Code:
"Invalid sparse file format at header magi error: write_sparse_skip_chunk: ([I]I forget the size[/I]) is not a multiple of the block size 4096"
So, after a bit of googling - I was going to try the SparseConverter tool.. but this seemed to not like the system-sign.img and so I gave up on that idea..
Then I realize I probably need to be using the SP Flash tool - so.. I boot back into Linux and here's what happens.. When the phone is turned on.. I can hold power on + volume up to get the little menu (flashboot, recovery or normal boot) and it ignores this... it goes right to Recovery with "NO COMMAND" - no combination of button pushing does a thing... it will sit at no command, occasionally flashing the screen. When i plug it in.. and don't touch it.. same thing.. straight to no command.. when I turn it on (not plugged in) it does the same thing... when connecting to PC and SP Flash... I hit DOWNLOAD in SP FLASH and then with phone off (battery in) I connect it to the the PC and i get the red bar to 100% and then:

found out how to unbrick!
OK!! SO... After a LOT of messing about I finally figured this out. What I did was start SP FLASH TOOL and put it in DOWNLOAD mode and then hit the DOWNLOAD button. I then connected the USB lead to my phone but NOT the PC (with the battery in the phone and the phone powered off) THEN I held down the volume up and volume down buttons together and kept holding them... I plugged the USB into the PC and kept holding the volume buttons... lo and behold it worked. I was too scared to let go of the volume buttons, so I just held them until the process had completed.
Hold volume down button when you plug usb lead in and hold until it starts flashing rom!
Also to enter recovery menu, press power + volume up when the command not found message appears.

Hi all,
I tried to flash the latest TWRP but for some reasons it's messed up. Now I can't enter recovery mode and just wondering if there is a way to re-install it.
I tried to do it via Fastboot mode but my PC(windows 10) can't recognize the phone when in Fastboot mode. I tried several ways(e.g. reinstall USB driver, remove / install driver via device manager, etc.) but no luck.
Any help/suggestion is appreciated.
Try with the original cable. It will work for sure. I had almost the same issue, tried various drivers, etc. Once I've connected the phone with its original cable, it was recognized instantly.
Strange, other people say, the original cable is bad quality??
I would use a different cable but an usb port on the mainboard no a front usb port.
Also i do all the adb und fastboot stuff on a linux machine, it's less struggeling with drivers then.
The original cable still works though, I'm not so sure what bad quality can that be... And yes, I haven't used it in these 3 years more than half of the time. In the past year I was using a 3m Ugreen cable which didn't do the trick for drivers, still working well.
However, with some changes in the kernel or whatsoever, the original cable doesn't charge the phone anymore while connected to the computer, but it ensures a good data transfer.
PS: USB type-C is more complex and not standardized for all manufacturers, which is a bit surprising, but that's it.

you need to format whole phone in oder to be recognized by pc.try first deleting all drivers for x2.go to windows in device manager,reboot pc and reconnect phone to pc by using usb type c cable
thank you for all the recommendations. I will try original cable and other PC using Linux and see if that works.
Update: My windows 10 PC installed the wrong driver when phone is in fastboot mode. Working fine now after deleting it from Device Manager and reinstalling.
